I have a squirrel feeder in my back yard that holds peanuts.
If the squirrels don't finish off the nuts by day, the raccoon raiders will do so in the middle of the night.
My weapon of choice to dispatch the bandits is an old Winchester model 67 bolt action rifle in .22 cal.
Quiet, and very accurate.
Not an option on a boat, but when they are hanging on a tree... :twisted:
